Note that I often included the entire group, even if only some species were cultivated. This is because if you look at some of the wild forms it's easily imaginable that similar plants can be cultivated as well. Just look at wild maize.

Also, I purposefully left out cacao and coffee. Both are luxury goods more than anything and can be substituted easily. While the same could be said for cannabis and tobacco, they are a bit more specific that you'd have a hard time supplanting them with something else. Having that said, I mostly included them for kicks and giggles. :P

Maybe? Do we have a rule-set yet? However we do it, I think there should be an "Ice Age" event from approx 110,000 ya to ~12,000 ya (see: Last Glacial Period). During this period there would be temporary landform changes like sea-level drops and advanced glaciation. I realize that that slightly crosses over into the next age, but that's okay because the areas with the most glaciation wouldn't have human settlements yet anyway.

Sorry guys still haven't got around to doing some proper rules for this (if you wait another couple of weeks I'll be done with all my asisgnments for the semester and can devote some time to it >_>).

I wouldn't set milestones by year. The rules for spreading dudes around will have a set level of cultural technology which triggers the next "age" and each turn will last a set amount of time, so the first city will be founded when people are advanced enough to found it, which may be sooner or later than it was historically on our world.

Been playing around with the map on Google Earth and I've come to the realization that aren't really places on the map for a Suez/Panama Canal situation. That being said, the age of sail should be more fun because of all the random subcontinents strewn all over the place.

Oh! Also we never got around to drawing in the ice caps! We should probably do that while we have some time waiting for rules to exist...
